5. Arthroscopic Surgery
With arthroscopic surgery, a surgeon will remove any pieces of a torn meniscus or bone fragments or cartilage that are continuing to cause problems. They will also repair ligaments that have sustained damage.
Arthroscopic surgery involves the use of a camera which lets the surgeon view the joint through a very small incision. Typically, anywhere from two to four incisions are made so that the surgeon can see all over the knee joint and easily perform the operation via the small incisions.
The technique is far less invasive then full-blown knee surgery. The incisions heal rapidly and most report far less discomfort
4. Plasma-Rich Protein Injections
Osteoarthritic knee pain sufferers have experienced benefits from plasma-rich protein injections (PRP). With the treatment, a small amount of blood is obtained from the sufferer and put through a process known as centrifuge, which quickly separates the platelets that are rich in growth factors. It is then injected into the knee.
3. Stem Cell Treatment
Bone marrow stem cells taken from the hip ease knee pain and help improve function. At this time, this treatment is rare and not typically recommended by experts.
